Abdullah bin Abbas reported,

"Allah is sufficient for us, and He is the best disposer of affairs" was said by Ibrahim when he was thrown into the fire, and it was said by Muhammad ﷺ when they said, "Indeed, the people have gathered against you, so fear them. But it only increased them in faith, and they said, 'Sufficient for us is Allah, and He is the best disposer of affairs.'" [Aal Imran 3:173]

حدثنا أحمد بن يونس أراه قال حدثنا أبو بكر عن أبي حصين عن أبي الضحى

عن ابن عباس

{حسبنا الله ونعم الوكيل} قالها إبراهيم عليه السلام حين ألقي في النار وقالها محمد ﷺ حين قالوا {إن الناس قد جمعوا لكم فاخشوهم فزادهم إيمانا وقالوا حسبنا الله ونعم الوكيل}
